We carry a selection of fuel flow sensors from Maretron, Lowrance, and Garmin. For example, Maretron's FFM100 provides precision fuel flow information to help optimize fuel consumption, which can save thousands of dollars in fuel operating cost. You can also add fuel flow information to compatible Lowrance/Simrad displays using the Lowrance 000-11517-001 Fuel flow sensor. The Garmin Gfs 10 Fuel Sensor adds fuel tracking capabilities to your Garmin chartplotter to optimize your boat's fuel economy. The GFS 10 tracks fuel flow use and sends the data to your chartplotter via the Garmin CANet or NMEA 2000. Whatever fuel flow sensor you need, we've got it here at a great price!
